I don't see any problem with your posting greenleaves. You are obviously unsure of what you believe in some areas, and there's nothing wrong with that.
Why not feel welcomed into the discussions of beliefs? You can easily tell your friends you haven't decided yet, and are interested in what they believe and why? They have those beliefs for a reason (or maybe not.)
For me, being friends and having compassion are not the same thing. I can have compassion on most anyone, and even for those I can't tolerate (such as child abusers) I can understand the why they might have done such.
From my studies as a Christian, God tells us not to judge those who are not professing to be Christians, that HE will do that. (We are to judge others who profess to be Christian but don't act like it, helping to bring them back in line with the teachings of Christ.)
I can be friendly with most anyone. Civility helps community.
